I have a summer house with a 60 year old cast iron toilet pipe and the original cast iron flange. The problem is the flange is below the old wooden floor level slightly and even with two wax seals we still are getting leakage. Two factors contribute to the problem other than the flange height: the floor is uneven and boards move a little and the toilet rocks slightly; second, the house is unheated during the winter and everything freezes. we have a bit of water damage to the 1" thick floor boards...so I may install a closet flange floor support. But my real question apart from doing a better job of shimming to get rid of the rocking: install a wax free toilet seal as made by Fernco or install a flange extender kit such as made by Set-Rite? All advice appreciated.
